2. Pants: Flat-front chinos. No “Dad pants” — the “shapeless, pleated tragedy” the wife of the San Francisco 49ers head coach Jim Harbaugh set out to eradicate. It’s OK to stray from the khaki-tan color grid. Take your dad shopping for some new pants while you’re at it.

3. Blazer: One jacket can fit all occasions: date night, weddings, job fairs. Unsure of what color to buy? Ask for advice. Invest a few extra bucks in this wardrobe staple.

4. Stylish T-shirt: Something without a sports team logo. This is where you can show your inner Zuckerberg, but without the hoodie.

5. Button-down shirt: It doesn’t have to be corporate blue or white. It can even be pink or plaid.

6. Tie: A tie speaks volumes. It says: “I’m a professional.” “I’m my own man.” It adds a splash of color to an otherwise drab outfit or tones down a plaid shirt. As our fashion model put it: “Even if you look crappy, it makes you look a little less crappy.”

7. Boots: Not mowing-the-lawn boots. A smart pair of boots such as Aldo will bring it up a notch, whether it’s with jeans or chinos.

8. Dress shoes: Something classic in black or brown shoe-polish colors with matching shoelaces. For when you can’t wear boots or sneakers. Or your mate tells you you can’t.

9. Watch: Bling it on. This is man jewelry. And it’s functional. For dressing up, get one with hands and a face, not bright green digital numbers.

10. Sunglasses: Good shades make a guy look cool, confident and sexy. Bad shades make him look 14. Splurge on some Ray-Bans.
